I've tested my code under workspace and it works. How come this doesn't work under challenge session?

Because it want the sentence Hi, I am Mike!. Your code would echo Hi, I amMike!. Do you see the error, and thus the solution? You're so close.

Even my version2 was not accepted.

<?php $name = 'Mike'; if($name == true){ //echo 'Hi, I am' .$name. '!'; $name = 'Hi, I am'.' '. $name . '!';

echo $name; } ?>

but anyway as long as i am absorbing and ending with correct results using workspace, that should be fine.

You're still not quite seeing it. You're missing a space in your echo statement. It wants am Mike, however you echo amMike. Thus your results is not passing. Do you see the error, and solution now?

understood of the solution and i see 2 ways of doing it. is this correct?

1. $name = 'Hi, I am'.' '. $name . '!';
2. echo 'Hi, I am ' . $name . '!';

as i undestand these 2 creates a space.

Sorry man, you're right, I got my eyes crossed when I looked at it. Yes, you are correct there. Because of the same reason I didn't catch your solution, option 2 would be the more human friendly way, and thus preferred way to add the space in the echo. But the computer doesn't really care either way....so good job!!

thanks Kevin. Now am learning!
